あった。The control circuit of a draw-out type breaker is connected to the switchboard using the conventional method (
1) By terminal block, (2) By plug connection,
(3) There are three types of automatic connection connections, and (2) and (31) are generally used most often. (3) is ideal in practice, but (2) is used for economic reasons. However, in the case of a plug connection, if it is a simple connection plug, it can be pulled out freely in any of the disconnection position, test position, and operating position, compared to a draw-out type breaker, so in some cases the connection plug may be inserted. There was a drawback that there was a risk of a situation in which the system was not properly maintained, resulting in a serious accident.

ことができるすぐれた効果がある。As described above, according to the present invention, a first connection plug for a movable control circuit, which is attached to a switchboard as a control circuit locking device for a draw-out type breaker, is connected to a second connection plug for a control circuit of a draw-out type breaker. When connected to the connection plug, the holding pin that protrudes in the insertion direction from the mounting plate on which the first connection plug is attached pushes the spring plate upwards. The locking pin, which engages with the holding pin and prevents it from coming out, and is fixed to the holding plate at the same time, is released from the recess, allowing the drawer-type breaker to be moved in and out of the switchboard. The plate has come off the holding pin and has been moved so that the first connection plug and the second connection plug cannot be separated, so if the control circuit is still connected, move the drawer breaker to the test position and operation position. unable to
When the draw-out type breaker is in the test position or operating position, the control circuit cannot be disconnected, which has the excellent effect of increasing safety and reliability.
